Description of problem: After enable CONFIG_X86_UP_APIC in kernel config file - kernel not compile. Version-Release number of selected component (if applicable): 2.4.21-9.0.1 How reproducible: make menuconfig and enable Local APIC support on uniprocessors Steps to Reproduce: 1. make menuconfig 2. enable "Local APIC support on uniprocessors" 3. make dep bzImage Actual results: arch/i386/kernel/kernel.o(.text.init+0x5321): In function `MP_processor_info': : undefined reference to `xapic_support_disabled' Expected results: kernel compile fine. Additional info: -
Sorry, but Red Hat does not support custom kernel builds. For the following reasons: - We are unable to effectively QA the infinite set of permutations and combinations of every kernel option. Consequently, it is impossible for support to differentiate the implications of every option. - There are a large set of 3rd party layered applications which have dependencies on RH kernel versions. - We produce periodic security errata, etc, which could then be conflicting with custom builds.
